Question

What would be the magnitude of a

Answer 1

The magnitude of a velocity vector is 60 m/s.

To find the magnitude, the given values are,

x - components = 36 m/s

y - components = 48 m/s

What is magnitude?

• The term magnitude can be defined as “ quantity ”.
• For instance, the magnitude can be used for describing about the comparison of speeds.

• It can also be used to explain the distance travelled by an object or to explain the amount of an object in terms of its magnitude.
• Magnitude of the velocity vector is total value which is square root of the value.

The magnitude of the vector can be,

| a | = √ ( x² + y² )

Substituting the values of x component and y component given,

      = √ ( 36² + 48² )

      = √ ( 1296 + 2304)

      = √ 3600

      = 60 m/s

The magnitude is found to be 60 m/s.

Hence, Option B is the correct answer.
